II. Background and Statutory Findings

    In the Federal Register of March 10, 2006 (71 FR 12356) (FRL-7761-
6), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 
4E6848) by IR-4, 500 College Road East, Suite 201 W, Princeton, NJ 
08540. The petition requested that 40 CFR 180.493 be amended by 
establishing a tolerance for residues of the fungicide, dimethomorph, 
(E,Z) 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propenyl] 
morpholine in or on Brassica head and stem (Subgroup 5A) at 2.0 parts 
per million (ppm). That notice included a summary of the petition 
prepared by BASF, the registrant. There were no comments received in 
response to the notice of filing.
    Supporting documents including the Agency's Human Health Risk 
Assessment of dimethomorph and other documents are available at 
www.regulations.gov under the index of the docket for this action, 
docket ID number EPA-HQ-OPP-2005-0537.
    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the

[[Page 76175]]

pesticide chemical residue, including all anticipated dietary exposures 
and all other exposures for which there is reliable information.'' This 
includes exposure through drinking water and in residential settings, 
but does not include occupational exposure. Section 408(b)(2)(C) of 
FFDCA requires EPA to give special consideration to exposure of infants 
and children to the pesticide chemical residue in establishing a 
tolerance and to ``ensure that there is a reasonable certainty that no 
harm will result to infants and children from aggregate exposure to the 
pesticide chemical residue....''
    EPA performs a number of analyses to determine the risks from 
aggregate exposure to pesticide residues. For further discussion of the 
regulatory requirements of section 408 of the FFDCA and a complete 
description of the risk assessment process, see https://www.epa.gov/
fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.

III. Aggregate Risk Assessment and Determination of Safety

    Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the 
available scientific data and other relevant information in support of 
this action. EPA has sufficient data to assess the hazards of and to 
make a determination on aggregate exposure, consistent with section 
408(b)(2) of FFDCA, for a tolerance for residues of dimethomorph on 
brassica, head and stem, subgroup 5A food commodities at 2.0 ppm. EPA's 
assessment of exposures and risks associated with establishing the 
tolerance follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered its 
validity, completeness, and reliability as well as the relationship of 
the results of the studies to human risk. EPA has also considered 
available information concerning the variability of the sensitivities 
of major identifiable subgroups of consumers, including infants and 
children. Specific information on the studies received and the nature 
of the toxic effects caused by dimethomorph as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at 
www.regulations.gov under docket ID number EPA-HQ-OPP-2005-0532; 
entitled, ``Amended: Dimethomorph: Human Health Risk Assessment for 
Proposed Uses on Brassica Stem and Head Subgroup 5A'', dated November 
15, 2006.

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable risk, the NOAEL from the toxicology study identified as 
appropriate for use in risk assessment is used to estimate the 
toxicological level of concern (LOC). However, the LOAEL is sometimes 
used for risk assessment if no NOAEL was achieved in the toxicology 
study selected. An uncertainty factor (UF) is applied to reflect 
uncertainties inherent in the extrapolation from laboratory animal data 
to humans and in the variations in sensitivity among members of the 
human population as well as other unknowns.
    The linear default risk methodology (Q*) is the primary method 
currently used by the Agency to quantify non-threshold hazards such as 
cancer. The Q* approach assumes that any amount of exposure will lead 
to some degree of cancer risk, estimates risk in terms of the 
probability of occurrence of additional cancer cases. More information 
can be found on the general principles EPA uses in risk 
characterization at https://www.epa.gov/pesticides/health/human.htm.
    A summary of the toxicological endpoints for dimethomorph used for 
human risk assessment can be found at www.regulation.gov under docket 
ID number EPA-HQ-OPP-2005-0532, entitled, ``Amended: Dimethomorph: 
Human Health Risk Assessment for Proposed Uses on Brassica Stem and 
Head Subgroup 5A'', dated November 15, 2006.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. Tolerances have been 
established (40 CFR 180.493) for the residues of dimethomorph, in or on 
a variety of raw agricultural commodities including: Brassica, leafy 
greens, subgroup 5B; lettuce, head; lettuce, leaf; potato, wet peel; 
taro, corm; taro, leaves; vegetable, bulb, group 3; vegetable, 
cucurbit, group 9; and vegetable, fruiting, group 8. Risk assessments 
were conducted by EPA to assess dietary exposures from dimethomorph in 
food as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk 
assessments are performed for a food-use pesticide, if a toxicological 
study has indicated the possibility of an effect of concern occurring 
as a result of a 1-day or single exposure.
     No such effects were identified in the toxicological studies for 
dimethomorph. A quantitative acute dietary exposure and risk assessment 
was therefore not conducted for dimethomorph. No acute risk is expected 
from exposure to dimethomorph.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the Dietary Exposure Evaluation Model software with 
the Food Commodity Intake Database (DEEM-FCID\TM\), which incorporates 
food consumption data as reported by respondents in the USDA 1994-1996 
and 1998 Nationwide Continuing Surveys of Food Intake by Individuals 
(CSFII), and accumulated exposure to the chemical for each commodity. 
In conducting a Tier 1 chronic dietary risk assessment, the Agency made 
the following conservative assumptions:
     a. All commodities having dimethomorph tolerances contain residues 
at the level of the tolerance, and
     b. Treatment of 100% of all registered and proposed crops.
    iii. Cancer. EPA has classified dimethomorph ``not likely'' to be 
human carcinogen. Therefore, a quantitative cancer dietary exposure and 
risk assessment was not performed.
    2. Dietary exposure from drinking water. The Agency lacks 
sufficient monitoring exposure data to complete a comprehensive dietary 
exposure analysis and risk assessment for dimethomorph in drinking 
water. Because the Agency does not have comprehensive monitoring data, 
drinking water concentration estimates are made by reliance on 
simulation or modeling taking into account data on the physical 
characteristics of dimethomorph. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at https://www.epa.gov/oppefed1/models/water/index.
    Acute and chronic estimated drinking water concentrations (EDWCs) 
of dimethomorph in surface water were calculated using Generic 
Estimated Environmental Concentration (GENEEC) Model. Drinking water 
residues were then incorporated into the DEEM-FCID(\TM\) into the food 
categories ``water, direct, all sources'' and ``water, indirect, all 
sources.''
    Based on the Tier 1 GENEEC and Surface Water and Screening 
Concentrations in Ground Water (SCI-GROW) models, the EDWCs of 
dimethomorph for chronic exposures are 28.5 parts per billion (ppb) for 
surface water and 0.30 ppb for ground water.
    3. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., for lawn and garden pest control,

[[Page 76176]]

indoor pest control, termiticides, and flea and tick control on pets).
    Dimethomorph is not registered for use on any sites that would 
result in residential exposure.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when 
considering whether to establish, modify, or revoke a tolerance, the 
Agency consider ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.''
    Unlike other pesticides for which EPA has followed a cumulative 
risk approach based on a common mechanism of toxicity, EPA has not made 
a common mechanism of toxicity finding as to dimethomorph and any other 
substances and dimethomorph does not appear to produce a toxic 
metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has not assumed that dimethomorph has 
a common mechanism of toxicity with other substances. For information 
regarding EPA's efforts to determine which chemicals have a common 
mechanism of toxicity and to evaluate the cumulative effects of such 
chemicals, see the policy statements released by EPA's Office of 
Pesticide Programs concerning common mechanism determinations and 
procedures for cumulating effects from substances found to have a 
common mechanism on EPA's website at https://www.epa.gov/pesticides/
cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408 of FFDCA provides that EPA shall apply 
an additional tenfold margin of safety for infants and children in the 
case of threshold effects to account for prenatal and postnatal 
toxicity and the completeness of the database on toxicity and exposure 
unless EPA determines based on reliable data that a different margin of 
safety will be safe for infants and children. Margins of safety are 
incorporated into EPA risk assessments either directly through use of a 
margin of exposure analysis or through using uncertainty (safety) 
factors in calculating a dose level that poses no appreciable risk to 
humans. In applying this provision, EPA either retains the default 
value of 10X when reliable data do not support the choice of a 
different factor, or, if reliable data are available, EPA uses a 
different additional safety factor value based on the use of 
traditional uncertainty factors and/or special FQPA safety factors, as 
appropriate.
    2. Prenatal and postnatal sensitivity. The toxicology data on 
dimethomorph provide no indication of enhanced sensitivity of infants 
and children based on the results from developmental studies conducted 
with rats and rabbits as well as a 2-generation reproduction study 
conducted with rats. There were no toxic effects observed in either the 
rat developmental toxicity or the rat 2-generation reproductive 
toxicity studies that were lower than doses which produced toxic 
effects in the parents. No developmental toxicity was demonstrated in 
the rabbit developmental toxicity study. The developmental and 
reproductive toxicity data did not indicate increased susceptibility of 
rats or rabbits to in utero and/or postnatal exposure.
    3. Conclusion. EPA has determined that reliable data show that it 
would be safe for infants and children to reduce the FQPA safety factor 
to 1X. That decision is based on the following findings:
    i. The toxicity database for dimethomorph is complete.
    ii. There is no evidence that dimethomorph results in increased 
susceptibility in in utero rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    iii. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100% crop treated (CT) and tolerance-level residues. Conservative 
ground water and surface water modeling estimates were used.
    Residential exposure to dimethomorph is not expected since there 
are no currently registered residential uses for the pesticide.

E. Aggregate Risks and Determination of Safety

    In examining aggregate risk, the Agency takes into account all 
available reliable information concerning exposures from pesticide 
residues in food and other exposures including drinking water and 
potential residential exposure to pesticides from such uses as lawn 
care applications (turf), golf course and others. Aggregate risk 
assessment considerations must also include potential exposures from 
oral, dermal and inhalation routes.
    1. Acute risk. No acute dietary toxicity endpoints were identified; 
no acute risk is expected from exposure to dimethomorph.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that exposure to 
dimethomorph from food + water will utilize 8.6% of the chronic 
population adjusted dose (cPAD) for the U.S. population, 7.0% of the 
cPAD for all infants < 1 year, and 19.9% of the cPAD for children -2 
years. There are no residential uses for dimethomorph that result in 
chronic residential exposure. Risk estimates for all population 
subgroups are below the Agency's LOC (do not exceed 100% of the cPAD).
    3. Short-term risk. Short-term aggregate exposure takes into 
account residential exposure plus chronic exposure to food and water 
(considered to be a background exposure level).
    Dimethomorph is not registered for use on any sites that would 
result in residential exposure. Therefore, a short-tern aggregate risk 
assessment is not required. The aggregate risk is the sum of the risk 
from food and water, which do not exceed the Agency's LOC.
    4. Intermediate-term risk Intermediate-term aggregate exposure 
takes into account residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level).
    Dimethomorph is not registered for use on any sites that would 
result in residential exposure. Therefore, an intermediate-term risk 
assessment is not required. The aggregate risk is the sum of the risk 
from food and water, which do not exceed the Agency's LOC.
    5. Aggregate cancer risk for U.S. population. Dimethomorph has been 
classified as a Group E carcinogen showing no evidence of human 
carcinogenicity. This classification was based upon lack of evidence of 
carcinogenicity in rat and mice studies. The Agency concludes that the 
pesticidal uses of dimethomorph are not likely to pose a cancer risk to 
humans.
    6. Determination of safety. Based on these risk assessments, EPA 
concludes that there is a reasonable certainty that no harm will result 
to the general population, and to infants and children from aggregate 
exposure to dimethomorph residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    A reliable method for the determination of dimethomorph residues in 
brassica, head and stem subgroup 5A exist; this method is the Food and 
Drug Administration (FDA) Multi-Residue Method, Protocol D, as 
published in the Pesticide Analytical Manual I. In addition, the method 
may be requested from: Chief, Analytical Chemistry Branch, 
Environmental

[[Page 76177]]

Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone 
number: (410) 305-2905; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

    There are no established or proposed Codex, Canadian or Mexican 
maximum residue limits or tolerance for dimethomorph in or on brassica, 
head and stem, subgroup 5A.

V. Conclusion

    Therefore, the tolerance is established for residues of 
dimethomorph, (E,Z) 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-
oxo-2-propenyl] morpholine in or on brassica, head and stem, subgroup 
5A at 2.0 ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes a tolerance under section 408(d) of 
FFDCA in response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled Regulatory Planning and 
Review (58 FR 51735, October 4, 1993). Because this rule has been 
exempted from review under Executive Order 12866 due to its lack of 
significance, this rule is not subject to Executive Order 13211, 
Actions Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use (66 FR 28355, May 22, 2001). This final rule does 
not contain any information collections subject to OMB approval under 
the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., or impose 
any enforceable duty or contain any unfunded mandate as described under 
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 
104-4). Nor does it require any special considerations under Executive 
Order 12898, entitled Federal Actions to Address Environmental Justice 
in Minority Populations and Low-Income Populations (59 FR 7629, 
February 16, 1994); or OMB review or any Agency action under Executive 
Order 13045, entitled Protection of Children from Environmental Health 
Risks and Safety Risks (62 FR 19885, April 23, 1997). This action does 
not involve any technical standards that would require Agency 
consideration of voluntary consensus standards pursuant to section 
12(d) of the National Technology Transfer and Advancement Act of 1995 
(NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Since 
tolerances and exemptions that are established on the basis of a 
petition under section 408(d) of FFDCA, such as the tolerance in this 
final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.) do not apply. In addition, the Agency has determined that this 
action will not have a substantial direct effect on States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government, as specified in Executive Order 13132, entitled Federalism 
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to 
develop an accountable process to ensure ``meaningful and timely input 
by State and local officials in the development of regulatory policies 
that have federalism implications.'' ``Policies that have federalism 
implications'' is defined in the Executive order to include regulations 
that have ``substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.'' This final rule directly regulates growers, food 
processors, food handlers and food retailers, not States. This action 
does not alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of section 408(n)(4) of FFDCA. For these same reasons, the Agency has 
determined that this rule does not have any ``tribal implications'' as 
described in Executive Order 13175, entitled Consultation and 
Coordination with Indian Tribal Governments (65 FR 67249, November 6, 
2000). Executive Order 13175, requires EPA to develop an accountable 
process to ensure ``meaningful and timely input by tribal officials in 
the development of regulatory policies that have tribal implications.'' 
``Policies that have tribal implications'' is defined in the Executive 
order to include regulations that have ``substantial direct effects on 
one or more Indian tribes, on the relationship between the Federal 
Government and the Indian tribes, or on the distribution of power and 
responsibilities between the Federal Government and Indian tribes.'' 
This rule will not have substantial direct effects on tribal 
governments, on the relationship between the Federal Government and 
Indian tribes, or on the distribution of power and responsibilities 
between the Federal Government and Indian tribes, as specified in 
Executive Order 13175. Thus, Executive Order 13175 does not apply to 
this rule.

VII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of this final rule in the Federal Register. This final 
rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
